• Predicting waves’ height, force could double marine-based energy

    In the search for alternative energy, scientists have focused on the sun and the wind; there is also tremendous potential in harnessing the power of the ocean’s waves, but marine energy presents specific challenges that have made it a less promising resource; one of these challenges is the fact that waves differ in terms of their size and force; forecasting wave height one second in advance optimizes energy collection

  • Next generation of advanced climate models needed

    From farmers deciding which crops to plant next season, to mayors preparing for possible heat waves, to insurance companies assessing future flood risks, to those responsible for infrastructure protection having to decide how best to use scarce resource to mitigate climate change-induced disasters, an array of stakeholders from the public and private sectors rely on and use climate information; the U.S. National Research Council says he U.S. collection of climate models should advance substantially to deliver more detailed, smaller scale climate projections

  • Urchin-loving otters can help fight global warming

    A thriving sea otter population that keeps sea urchins in check will in turn allow kelp forests to prosper; the spreading kelp can absorb as much as twelve times the amount of CO2 from the atmosphere than if it were subject to ravenous sea urchins

  • Scientists question earthquake prediction methods

    From 2008 to 2011, three earthquakes have significantly damaged different parts of the world. Those quakes were significantly underestimated by scientists and seismologists

  • Destroyed coastal habitats produce significant amounts of greenhouse gas

    Destruction of coastal habitats may release as much as one billion tons of carbon into the atmosphere each year, ten times higher than previously reported; a new analysis provides the most comprehensive estimate of global carbon emissions from the loss of these coastal habitats to date: 0.15 to 1.2 billion tons; it suggests there is a high value associated with keeping these coastal-marine ecosystems intact as the release of their stored carbon costs roughly $6-$42 billion annually

  • Coastline erosion due to rise in sea level greater than previously thought

    The effects of coastline erosion as a result of rising sea-level rise can be measured by acceptable engineering tools, but such an erosion in the vicinity of inlets, such as river estuaries, has until now been underestimated – and more difficult to calculate; scientists have develop a new model to calculate this more complex erosion, making a valuable contribution to coastal management, planning, and infrastructure protection

  • MIT expert: “toxic” political discussions limit climate response

    In a talk at the Sandia National Lab, an MIT expert says the inability of natural and social scientists to convince political leaders that “we’re spinning a roulette wheel over climate change” puts humanity at “extreme risk,” and that the difficulties in using science to push for mitigation strategies are more political than scientific

  • Trade-offs between water for food and for curbing climate change

    Earth’s growing human population needs fresh water for drinking and food production. Fresh water, however, is also needed for the growth of biomass, which acts as a sink of carbon dioxide and thus could help mitigate climate change. Does the Earth have enough freshwater resources to meet these competing demands?

  • As Hurricane Isaac beats on New Orleans, new infrastructure is holding up

    This week, as Hurricane Isaac was threatening to replicate the physical damage that Katrina inflicted, it has become apparent that $14 billion worth of changes and improvements in infrastructure, planning, and emergency response procedures have given the city of New Orleans and the Gulf states the ability to withstand the worst of the storm

  • Isaac leaves flooding, power outages in its path

    Hurricane Isaac lost its Category 1 hurricane status midday Wednesday and was downgraded to a tropical storm, but the severe rains and winds which it brought with it have not let up much; the number of power outages continues to increase as the number of homes and businesses without electricity is now up to 834,000 between Louisiana, Mississippi, Alabama, Florida, Texas, and Arkansas, with over one-third of the outages in Louisiana alone

  • Drones being used to track hurricanes

    Federal hurricane trackers will start experimenting with unmanned boats and aircrafts to learn more about how to anticipate and track the movements of hurricanes; NASAand the National Oceanic and Atmospheric Administration(NOAA) are teaming up and using a pair of military-surplus Global Hawk spy drones, which are known more for spying on battlefields than chasing storms

  • Underground organisms play a more complex role carbon capturing than previously thought

    In a surprising finding, researchers have shown that certain underground organisms thought to promote chemical interactions that make the soil a carbon sink actually play a more complex, dual role when atmospheric carbon levels rise

  • Evaluating fresh water sustainability in the southern U.S.

    Researchers have embarked on 4-year federal research effort to evaluate freshwater sustainability across the southern United States and develop policy recommendations on what can be done to make the best use of water supplies in the face of population growth and the effects of climate change over the next ten to thirty years

  • Hurricane Isaac downgraded from Category 1 hurricane to tropical storm

    Hurricane Isaac was downgraded from a category 1 hurricane to a tropical storm. The storms winds have dropped below 70 mph, but the storm is moving very slowly throughout the gulf area at about 6 mph; at this point officials estimate that Isaac is expected to cause $1.5 billion in insured losses

  • New Jersey infrastructure badly needs shoring up, and soon

    According to experts, changes to the way New Jersey maintains its infrastructure must be made soon, or the state could be vulnerable to catastrophic failures in its water and power systems as well as collapsing roads; the North Jersey Transportation Planning Authority says more than $56.9 billion will be needed just to maintain state roads, rails, and public transportation systems through 2035; when you add in improvements to account for environmental changes and the expanding population in the state, the bill skyrockets to more than $123 billion
